There are two Olympic disciplines: Greco-Roman wrestling and men's freestyle wrestling. Click on one of the images below or scroll down to find out more about each discipline.
Greco-Roman wrestling sees two male competitors compete in two-three minute periods. The aim of each wrestler is to pin their opponents shoulder to the mat and should they achieve their goal, they are awarded the victory by a “fall”. The wrestlers aim to pin their opponents by using throws, locks and clinching techniques, but are only permitted to use their upper body to achieve the holds.
If they are unable to achieve a win by fall the contest continues until the end of the second of two three-minute periods. At the close of regular time the winner is decided according to the technical points scored, with a takedown scoring between one to five points should they gain control of least three points of their opponent’s body on the mat.
A wrestler can score a point through a reversal, gaining control from a defensive position. Should they expose their opponents back to the mat they can be awarded between two or three points. Penalties of one or two points can be given for injuring or endangering an opponent, while stepping out of bounds is punished by a one point penalty.
Only men compete in Greco-Roman in the Olympics and will contest the following weight divisions at Rio 2016: 59kg, 66kg, 75kg, 85kg, 98kg and 130kg.
While Greco-Roman wrestling only allows the use of the upper body, all freestyle holds can involve the legs in order to ultimately pin the opponent's shoulders to the mat. If a wrestler manages to do so, they win by a fall.
Should neither competitor achieve that the match continues until the end of the two three-minute periods. The winner is then decided according to the technical points scored with points awarded in the same fashion as Greco-Roman. A point can also be awarded, though, to an attacking freestyle wrestler should their opponent flee or refuse to start a hold.
Both men and women compete in freestyle events.
The men will compete at Rio 2016 in the following divisions: 57kg, 65kg, 74kg, 86kg, 97kg and 125kg.
The women will compete in: 48kg, 53kg, 58kg, 63kg, 69kg and 75kg.
